48S257 - Walter M6x20 Socket Head Cap Screw Replacement Part

Genuine Walter Replacement Fastener

The Walter 48S257 Screw TCEI M6x20 is a premium-grade replacement fastener designed specifically for Walter Surface Technologies equipment. In the demanding world of industrial metalworking, the integrity of every component in your power tools and machinery is critical. This genuine OEM part ensures that your Walter grinders, finishing tools, or cleaning systems maintain their structural rigidity and operational safety. Unlike generic hardware store fasteners, this screw is manufactured to the precise tolerance and material specifications required by Walter's engineering standards.

Technical Specifications and Design

This fastener features a TCEI design, which stands for "Testa Cilindrica Esagono Incassato"—internationally known as a Socket Head Cap Screw. It utilizes a standard metric M6 thread and has a total length of 20mm. The cylindrical head with an internal hexagonal drive allows for high torque application using an Allen key, ensuring a tight and secure fit without the risk of cam-out associated with Phillips or slotted screws. The compact head design is ideal for recessed holes or tight spaces within machine housings where a protruding hex head would be obstructive.

Importance of OEM Parts

Using genuine parts like the 48S257 is essential for maintaining the longevity of your equipment. Mismatched screws with incorrect tensile strength or slightly off-pitch threads can damage internal tapped holes, leading to costly repairs or tool failure. This screw is crafted from high-strength steel, providing the necessary shear resistance to withstand the vibrations and stresses common in heavy-duty grinding and finishing operations. Whether you are performing routine maintenance or an emergency repair, trusting genuine Walter parts guarantees compatibility and performance.

Application and Installation

This screw is typically used to secure housing components, guards, or internal mechanisms within Walter power tools. Installation is straightforward using a standard metric hex key. Users should ensure the receiving threads are clean and free of debris before installation to prevent cross-threading. It is recommended to consult your specific tool's exploded view diagram or service manual to confirm that the 48S257 is the correct part number for your specific model and location on the tool.
